To all whom it may concern-f Be it known that I, Yoiiioi-irKrNosi-irrfi, a subject of the Emperor of Japan, residing at Boston,county of Suffolk, State oi lviassachusetts, have made a certain new anduseful invention in Dumping-Truck Apparatus, oip4 which the following isa specification. Y i V This invention relates to dumping truckapparatus. Y

The obje'ft oic the invention is to provide truck body or truck bodysupport and operating apparatus therefor which is simple in structureand efficient in operation whereby the truck body may be rocked or swunginto any desired angular relation with re- `'peet to the' chassis andthe tilted so as to dump the contents of the body.

A further object of the invention is to provide means to .preventlateral tipping 01' the truck body or its support.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination',location, and relative arrangement of parts, all as will be more `fnllyhereinafter set forth, as shown Vin the accompanying drawings, finallypointed out in the appended claims.

Referring to the accompanying drawings:

Vtruck struct-ure which is simple `and eiiicient,

whereby the truck body or its support may be rocked orswung `intoany'desir'ed angular relation with respect to its supporting chassistraine, vand when swung into the desired po-` sition of' angularitywith. .respect to Said frame, may be tilted so as to dump or deliver thecontents of the body, andthereafter agailn lowered andreturned to itsinitial position.

. Ordinarily a truck body is positionedupon the chassis fra-ine of thetruck in longitudinal alignment or relation with respect to the chassis,and it is a common practice to so mount such a bodyk as' to permit thesame to be rocked or tilted vertically-to effect a dumping of thecontentsY or" the body. ln

limits the utility and application of dumptruck bodies. Occasions andsituations 'frequently occur where 'it isdesirable to dump the contentsof abody at an angle to the line of the chassis frame sol as to deliversuch contents toa more coirivenientV point on a loading platform,sidewalk, or 1 other in carrying out iny invention l provide a chassisframe 10, which may be of any suitable or convenient construction, andconstituting the fixed supporting part of a truck or trailer, or thelike, being supported upon the usual. axles 11 and wheels 12. Mountedupon the chassis trame is what Twill term a turntable 13. This turntableis mounted to swivel or turn about va vertical axis aorded bya studshaft le suitably journaled in the chassis iframe. Pivotally mounted atone end of the turntable is a vertically extending guide frame 15. Alsopivotally mounted upon the turntable, but at the opposite end thereof,is a. tilting platiorni l. Y it its front end the tilting platform 16 ishingedly connected to a slide block 17 mounted to slide for the guidemember of the turntable to abut thereagainst alter the desired extentof. the swinging movement of the turntable has been attained.v

lt may occur that when'the turntable 13V turned to a position roximatelat 1 Y .Y y, rient an les tothe chassis trame and when b v n a teioor erisle vr caik o Lh Ll memb 16 tlt d e ti lll t etlect a dumping of theload, and particu-Y larly where the truck is heavily-loaded, a tendencyis developed to tilt the entire truck over laterally in the direction ofthe inclination of the tilting floor member i6, that is, a. tiltingstress is imposed upon the entire tdruclrtending to overturn itsidewise. l propose, in accordance with my invention, to provide meansfor preventing this, and have shown one simple illustrative arrangementfor accomplishing the desired purpose lwherein the turntable 13 isprovided with longitudinally extending guide slots 56 in the guidemembers ofthe turntable near the rear end thereof, and supporting legs57 are mounted upon the turntable and are provided with projections orextensions V58 which slide along the slots 56. rEhe slots 56 areenlarged at their rearmost ends as indicated at 59 so that when thesupporting legs 57 are drawn out or extended the projections 58 thereonare permitted to swivel or turn in the enlarged portions 59 soas topermit the extended legs to tilt downwardly into vertical position, asshown in dotted lines in Fig. 7, to engage the ground or pavement, andhence form a support Vfor 'the structure to'prevent the same fromtipping over. v Y* Y 7While the propelling motor for the truck may beemployed to drive the-power Shaft 19y and the gearing requiredforeifecting .the swinging movements of the turntable and the tiltingmovements of the floor member 16, it is obvious that my invention is notto be restricted or limited in this respect, said gearing Amay beI powerdriven from any suitable or convenient source, and my inventio'n in itsbroadest aspects is not concerned with'the Source ot power from whichthe gearing referred to is driven.

It is believed 'that the operation ot the apparatus will be fully/'andclearly understood romthe toregoing'description. Assuming that theturntable 13 and the tilting platform or flooring 16 are in their'normal ant. retracted positions, as indicated for example in fulllinesin Fig. 1` and a load or a loaded body is imposed upon the rlooring16,the truck is Ythen driven in the ordinary way to the point where theload Yis to be delivered and unloaded. It the unloading station orplatform is a Sidewalk,

Vfor example, the truck is driven to a position parallel with the curbof the sidewalk. The stop device 58 is then adjusted tov a point suchas'to form a stop for the turning movements of the turntable 13 at thedesired angle of inclination or turning movement thereof. Thecountershatt 2O is then geared to the source of power and rotationimparted thereto. Through the worm gearing 26, rotations are imparted tothe bevel gear 30. lt the latch devices 51, 52, are detached, the first-eilect of the rota` tion of bevel gear 30 is to impart a swingingmovement to the turntable coincidently with the rotation of the bevelgear; lfhisV swinging movement continues until the frame or' theturntable abuts against. a stop device orl is otherwise arrested, as,#for instance,y the stop lug 53. When this point is reached, and thefurther swinging movement of the turntable is arrested, the continuedrotation of the bevel gear: will impart rotation to 'thegear wheel 32which meshes therewith, thereby rotating shaft 31, andhence operatingthe drums 36, 37causing thefcable to wind up on said drums, and henceelevating the iront end of the tilting platform or looring'l so as todump" or discharge the load. llilhen the unloading has been completedthe gearing is reversed, and thereupon `the iirst action is to cause thetilting flooring member 16 to be lowered back` into initial positionyupon the turntable, and when this movement is completed the turntablewill be automatically swung around again to thedesiredextent to attain aposition where it may againbe latched or fastened to the chassis frame.

It will beunderstood ofcourse that'the swinging'movements of `theturntable may likewise bevutilized for conveniently loading a truckor't'ruck body from a point at the side of the truck frame. 'Y i It willbe seen from; Figlia that the gear 30 is journaled to rotate uponthestud 1d, which is mountedk in the chassis ytrame.

cured to the'chassis trame'and the turntable, so that when the lsaidgear is rotated the turntable is rictionally driven therewith. Duringthis movement ofcourse the gear 32, and its shaft/31, are carried withthe turntable, and hence are not axially rotated. When, however, therotative movementv of the turntable is arrested, the continued rotationof the gear 30 overcomes the friction ott the clamping plate or member51, and hence the gear 32 and shaft 31 will thereupon be axiallyrotated, thereby causing the slide 17 'to move along its guide in theguilde member 15, and hence causing the platform i6 to be .tilted aboutits hinge connection to the turntable. f Many variations and changes inthe details of construction Vand arrangement ywill readily occur topersons skilled in the art and still tall within the spirit and scope ofmyy invention, but having now set forth the ber, and connected to saidplatform, cable devices connected to said slide to move the same, a gearconnected to said table to rotatively move the same, a shaft mounted insaid table and connected to said gear, and means driven by said shaft toactuate said cable devices.
